v0.2.2 - compare the peeled tag commit so re-runs are a no-op

[0.2.2] - 2026-10-15

Fixed

• npm run release compared the tag with HEAD through the bare ref, which for
  an annotated tag yields the tag object rather than the commit it marks — so
  a tag that did point at HEAD was reported as pointing somewhere else, and
  re-running a finished release failed. It now compares the peeled commit
  (refs/tags/v<x.y.z>^{commit}). As a result a completed release is a clean
  no-op: the push and the tag are skipped and the existing GitHub Release is
  reported instead of being posted a second time.

Added

• test/release.test.js pins the peeling down against a throwaway repository.
